Changes in v12: A new patch (part 2/7) is added to this series. Part 6/7: - change the description of 'compatible' property according part 2/7; - improve the document according Gerhard's feedback; Parts 1/7, 2/7 and 4/7 have been applied by Vinod Koul and are excluded from v13. Changes in v13: A new patch (part 1/5) is added to this series. Part 2/5: - fix style issue; - improve comments; > known issues: > - it's yet to get confirmed whether MPC8308 can use slave support or > whether the DMA controller's driver shall actively reject it, the > information that's available so far suggests that peripheral transfers > to IP bus attached I/O is useful and shall not get blocked right away Alexander Popov (5): dmaengine: fix comment typo dma: mpc512x: add support for peripheral transfers dma: of: add common xlate function for matching by channel id dma: mpc512x: add device tree binding document dma: mpc512x: register for device tree channel lookup .../devicetree/bindings/dma/mpc512x-dma.txt | 40 ++++ arch/powerpc/boot/dts/mpc5121.dtsi | 1 + drivers/dma/mpc512x_dma.c | 257 ++++++++++++++++++++- drivers/dma/of-dma.c | 35 +++ include/linux/dmaengine.h | 2 +- include/linux/of_dma.h | 4 + 6 files changed, 332 insertions(+), 7 deletions(-) create mode 100644 Documentation/devicetree/bindings/dma/mpc512x-dma.txt -- 1.8.4.2
